| Abstract: | Rigid Frame-continuous composite girder bridge requirement a process that temporary consolidation of the pier beam removal of system transformation,this bridge belong to a statically indeterminate system,the removal of temporary consolidation will impact for the bridged’s displacement and stress of bridge structure.Explore the impact of the bridge’s temporary removal of the consolidation order on the structure,in order to achieve the purpose of optimizing the closure program,and to provide the appropriate reference for the temporary consolidation of such bridges in the future dismantling program. |
